First of all, thanks to Lei Feng for letting me know that the charger can also be used to install B. I have heard of wireless charging before, but I don't know its principle.

Science popularization:

The wireless charging technology mainly uses electromagnetic technology to convert the current into electromagnetic at the transmitter, and the mobile phone or external wireless charging device converts the electromagnetic into current through the receiver to charge it. Up to now, the whole world Within the range, the mainstream wireless charging standards are divided into: Qi wireless charging PMA wireless charging and WPC wireless charging technology.

Qi wireless charging standard (referred to as WPC or "Qi standard" by Wireless Power Consortium) adopts electromagnetic induction technology, which is more efficient and safe than other technologies More advanced. Nokia was the first to adopt this technology. Nokia Lumia series basically adopted the Qi standard, followed by Samsung Google and others began to use it. In addition, PMA (Power Matters Alliance), Alliance for Wireless Power (A4WP standard), etc.

Speaking of wireless charging, its biggest advantage is that it is easy to use. It does not need to drag a "long tail" when charging. If you need to use a mobile phone during daily charging, you don't need to Just place the phone on the wireless charging plane.

Because many devices do not support wireless charging, because there is no built-in wireless charging module, it is better than my own Meilan note2. Without much talk, direct dry goods:

packing

Front: Grey paper, without plastic film, feels good and is environmentally friendly. The design is very simple, which is too simple to understand (I am a graphic designer, and of course I can also do packaging design). On the right is wireless charging Paste (This can be understood as the wireless charging module in your mobile phone).

The reverse side: parameter specification, input: 5.0V-2A, output: 5.0V-1A. It is estimated that many people do not know the meaning, many colleagues around me do not know it, and I have only recently learned it. General meaning Why: The charging head of old mobile phones (function phones) is 5v-500ha, and that of general smart phones is 5v-1a. At present, the charging head of mobile phones with large capacity batteries of 3000ha is 2a. Of course, there are also those that support fast charging 4a. That's my magic blue note2，3000ha， It takes 6 hours to charge with a 500ha charging head, 3 hours to charge with a 1a charging head, and 1.5 hours to charge with a 2a charging head (this is only an estimate of the time, which is generally longer than the theoretical time Longer).

The whole packing box is thin enough to be torn from "open".

The inside of the package (the second cover) is printed directly as the instruction manual. After opening the "title page", you can see the main body of the wireless charger lying in the package. The oblate shape reminds me of the coaster. It's very textured Coasters, leather.

thin

Because the charger is thin, the package is also thin. It's all thin. Who doesn't like thin chargers (coasters)?

This white one can be understood as double-sided adhesive tape

The back of the charger is made of stainless steel and charging parameters.

This is a wireless charging sticker. This step is very important. But I didn't say the function of the double-sided adhesive tape.

Wireless charging sticker The manual said that "W wave pattern" should be upward. The stripe line is good, which reduces the volume of the line.

Now, insert me Meilan note2 mobile phone.

Not really "W wave pattern" upward?

Therefore, even if Meilan note2 is charged, it fails because the line is twisted (see the bottom socket).

Xiaomi 2s success

Little Coolpad Success

Therefore, according to the above experience, the charging port of the mobile phone should be at the bottom, must be in the middle, and the T-shaped port should be downward. (For portability)

Xiaomi 3 failed. The reason is that the socket is biased, so: there is not enough line for hooking fish on the plane.

ZTE N880 failed because the socket is on the side. You can compare your mobile phones to see if they can be charged.

Note: According to its charging principle, the wireless charging sticker does not need to tear the adhesive. It is not necessary to put it on the back of the phone against the battery. The charging sticker can be separated from the phone. However, in consideration of portability, the above test results that cannot be charged or is not convenient for charging are given.

charge

The charging speed is about the same as that of the ordinary socket, and the pin may be a little longer. It should be noted that the phone can be put on and The charging time is 2-3 seconds. So it can't be too urgent. It's not like ordinary wire charging. It lights up when plugged in.

summary

First, thin; Do not occupy space.

Cortex; It blends into life and feels great.

Third, unlimited B, wireless charging. If it is used in the office area, the little MM who has never seen wireless charging will look curiously and put his mobile phone on your small DD (mat).
